Green Software Brighton - speaker template designs

**Why**: So far I have been creating our speaker cards by hacking away at Jenya's lovely designs. Sorry Jenya!

**What**: Can Jenya design two speaker templates for us that I could edit on a month by month basis. (1) for a single speaker and (2) for two speakers. Perhaps this is something that is useful for all meetups or already exists? Examples of what I have done before now are

**Scope of Work:**
It would be great if we could request
- [ ] rectangular version 1200x676 px?
- [ ] square version 1080x1080 px?

@Jenya-design would that be possible? Is Canva an option or do you think there is a better way?
